ProFTPD 1.3.2rc3 - 1.3.3b Telnet IAC Buffer Overflow (FreeBSD)

This module exploits a stack-based buffer overflow in versions of ProFTPD
server between versions 1.3.2rc3 and 1.3.3b. By sending data containing a
large number of Telnet IAC commands, an attacker can corrupt memory and
execute arbitrary code.
